Does the WebP stay animated, or do I just get one frame?

It stays animated. Every frame and the timing between them are preserved, so your clip plays and loops exactly like the MP4 did — just as a single image file. If you'd rather pull one still moment out of the video instead, switch the output to still WebP and use the frame picker to choose the exact frame.

Is an animated WebP smaller than a GIF of the same video?

Almost always, and usually by a wide margin. WebP uses far more efficient compression than GIF and supports full color, so you get a much smaller file that also looks better — no 256-color banding or dithering. For short, looping clips it's the better choice on nearly every count.

What happens to the audio in my MP4?

It's removed. Animated WebP is an image format and can't carry sound, so the converter drops the audio track automatically. If you need the audio to come along, convert your MP4 to WebM instead — that's a true video format with an optional sound track.

Where can I use an animated WebP once it's converted?

Anywhere you'd use an image. Every current major browser displays animated WebP, so you can drop it straight into a website, app or README with a normal image tag and it loops on its own. Email clients are more mixed, so test there or keep a fallback. A few older apps and some social platforms still prefer MP4 or GIF, so keep your original in case you need to re-export.

Do I need an account, and is there a watermark?

No to both. Converting MP4 to WebP is free, anonymous and watermark-free — nothing is stamped on your clip and there's no signup. Your upload and result are deleted from the server about an hour later. A free account is optional, and a one-time Pro upgrade adds extras like a permanent library, reusable presets, batch conversion, and bigger uploads.

Drop in an MP4 and LightBox turns it into an animated WebP that loops on its own — no video player, no play button, no autoplay rules to fight. It's the format you reach for when you want a short clip to behave like an image: a product demo on a landing page, a hero loop, a README walkthrough, or a reaction clip that plays inline the moment it appears.

If you've been exporting clips as GIF, animated WebP is the straight upgrade. It keeps the same set-it-and-forget-it looping, but with real color depth instead of GIF's 256-color banding and a file that's a fraction of the size. Your MP4's gradients, skin tones and screen recordings stay clean instead of turning grainy.

Upload happens right in your browser, FFmpeg does the conversion on our server, and you decide how it looks before you commit — frame rate, quality, trim to just the seconds you need, crop, resize and loop count. Audio is dropped automatically, since animated WebP is silent by design. No signup, no watermark, and your files are deleted from the server about an hour later.

Far smaller than a GIF, far sharper

Animated WebP was built to fix everything GIF gets wrong. The same loop comes out dramatically smaller, so pages load faster and your clip stays under email and chat limits — and full color means no posterized gradients or dithered noise. You get the convenience of a GIF without the visual cost.

Plays inline, no video player needed

An animated WebP drops into an image tag and simply runs — it autoplays, loops, and needs no controls, no codecs and no user tap. That makes it ideal for hero sections, feature demos, docs and many HTML email clients, where a real video element would be blocked, clunky, or just overkill.

Tune the trade-offs before you download

Set frame rate and quality to balance smoothness against size, trim to the exact moment that matters, then crop, resize and choose how many times it loops. It's the difference between a bloated export and a tight, web-ready clip — and you make those calls up front instead of guessing.
